摘要：
The method of obtaining crystals of thiourea from water solution at room temperature was described. The results of the measurements of the elastic constants by means of Brillouin scattering were presented. It was shown that there exists a correlation in orientation between the tensors describing elastic properties and thermal expansion. Debye's temperature and components of the tensor of Gruneisen parameter of the thiourea crystal in the V polimorphic modification are determined.
